After giving a concise overview of all members of the Anatolian language family, this chapter offers an in-depth discussion of the family’s phylolinguistic make-up. It discusses all major linguistic arguments on the basis of which it can be determined that Anatolian is a single branch within the wider Indo-European language family, as well as the linguistic arguments that can be used for drawing a family tree of Anatolian. It is argued that the first split in the Anatolian branch is between the Hittite branch and a branch that comprises all other Anatolian languages. In the latter branch, first Lydian and then Palaic split off, after which the remaining language develops into Proto-Luwic, the ancestor of the Luwian and Caro-Lycian branches. This phylolinguistic reconstruction of the Anatolian family includes a discussion of the possible dates of all nodes in its tree and of its Proto-Anatolian ancestor language. The chapter also assesses the place of Anatolian within the Indo-European family as a whole on the basis of a discussion of possible closer relationships between Anatolian and other branches of Indo-European, as well as of the Indo-Anatolian hypothesis.
